Contribute Data to PACT/R

If you have a question about whether your dataset is appropriate for the PACT/R Data Archive, please contact us at childtraumadata [at] email.chop.edu.

Why contribute data to the PACT/R Data Archive?

Most importantly, contributing data to the Archive helps sustain this important resource for the field, and helps to promote collaborative efforts to advance our knowledge of child trauma.

Investigators who have contributed their data most often do so with the goal of supporting this international data sharing effort. Investigators who contribute datasets to the Archive will receive regular updates on the status and use of the PACT/R Archive.

In addition, submitting data to the Archive can help investigators meet data sharing requirements from their funders.

Does contributing a dataset affect ongoing analyses of these data by my team?

Contributing a dataset to the PACT/R Archive does not affect the ongoing analyses conducted by the original research team.

In contributing data, the investigator must agree that these data will eventually be available for request by other qualified researchers. However, if funding requirements or specific analytical needs require that access to a given dataset be temporarily restricted, the PACT/R team is happy to discuss this with the contributing investigator.

What is involved in preparing a dataset for submission?

Download guidance for "How to prepare and submit a dataset" for updated information on preparing data for submission to the PACT/R Archive.

What about ethics approval?

Studies from which data are drawn must have been conducted with appropriate ethics board approval (for example, IRB approval for US-based studies). We require documentation of this approval as part of the data submission process. Depending on local or national regulations, the act of submitting de-identified (anonymized) datasets to the PACT/R Data Archive may not require approval by an ethics board / IRB. It is the responsibility of the original investigator to determine whether such approval is required by their institution's ethics body, and if required, to secure approval for submission of their dataset to the PACT/R Data Archive.

What datasets can be contributed to the PACT/R Data Archive?

The primary aims of this data archive are to support research that increases understanding of risk and protective factors and symptom trajectories for psychological sequelae (including PTSD) in children and adolescents.

Thus, in order to be included in the archive, a study dataset must have:

a) at least one predictor (i.e. a potential risk or protective factor) assessed within 6 months of the event (ideally with a baseline assessment within 1 month of event), and

b) at least one assessment of traumatic stress or other psychological sequelae one month or more after assessment of predictor(s)

Additional assessments of potential predictors and of relevant outcomes are desirable.

A note about intervention studies

Intervention studies are extremely valuable, but by definition are designed to introduce intervention-related changes that make it more difficult to track the natural course of recovery and post-trauma difficulties.

The PACT/R Archive accepts datasets from intervention studies with intervention conditions clearly coded, and clearly described.

Types of studies / datasets that may not be appropriate for inclusion in the PACT/R Archive

  • Studies in which children were recruited because they are experiencing post-trauma psychosocial difficulties (i.e., treatment-seeking samples)
  • Chronic trauma as the index trauma / reason for recruitment

Nearly all samples of children exposed to an index acute trauma will include children who have also experienced some degree of chronic or relational trauma. This is completely appropriate and useful for understanding the range of responses to acute trauma, and is not an exclusion criterion for the PACT/R Archive.

However, when study participants are identified based solely / primarily on their exposure to chronic or relational traumas (e.g., child abuse, prolonged refugee or war / conflict experiences), the dataset is generally not appropriate for the PACT/R Archive. Understanding the impact of chronic trauma on children is vitally important, but is not currently the focus of this archive.
